Police were questioning a person of interest in Athens, Georgia, Friday, just 24 hours after they found a nursing student dead when she failed to return home from her morning jog, according to a University of Georgia official.
"University of Georgia police have identified a person of interest who is being questioned," UGA's Office of Marketing and Communications told Fox News Digital. "We want to stress this continues to be an active ongoing investigation, and we will provide updates as circumstances warrant."
A concerned friend called police for Laken Riley on Thursday around noon. The 22-year-old former University of Georgia student who was enrolled at the neighboring Augusta University in Athens had gone for a run through UGA's Intramural Fields that morning and never came back.

Within minutes, campus police found her body near Lake Herrick. She had "visible injuries" and authorities launched a homicide investigation.
After police announced they were questioning someone in the case, Riley's family members broke their silence with a post on her sister's Instagram.
This isn’t fair, and I will never understand it.
"The best sister and my built-in best friend from the very first second," her sister, Lauren Phillips, wrote. "This isn’t fair, and I will never understand it, but I know you are in heaven with the man you loved most right now. I’m not sure how I’m going to do this but it’s all going to be for you from now on. I cannot wait to give you the biggest hug someday. I will miss and love you forever, Laken."
"I thank God every day that you are a part of my life. You were the best friend, roommate, dog aunt, dancer, banner chair, sister, hair curler, student, advice giver, and so much more," her roommate, Sofia Magana, wrote. "Laken, I am so honored to call you my roommate and best friend. I love you more than words can describe, and I can’t wait to give you the biggest hug and kiss on the cheek one day. I love you forever."
University police led the investigation with help from the Georgia Bureau of Investigation and Athens-Clarke County police.
